I have a nikon d7100 camera and photoshop elememnts 8. At present I cannot open the NEF files into elements 8. What is the solution? If I have to upgrade to elements 11 - will this software do the trick (or is there any other option?)
You have 3 choices, 2 of them are free

You need to "read up" on Adobe Camera Raw (ACR), how the versions change as cameras are introduced, how ACR versions apply to versions of PSE and, generally how the various versions of "RAW" files are translated to something viewable.
The short version is that your 7100 is so new it was not included until ACR 7.4, the last of the 7.x series. To use any version of the 7.x series you need PSE 11. Earlier versions of PSE won't accept the 7.x series.
Adobe DNG Converter upgraded to 8.1 last week. 7.4 is history!
